The reason of current problem lies inside projection algorithm
Function_SetUVBounds() for projection of circle onto sphere produces shifted bounds.
Incorrect checking of placement on summit of the sphere was fixed.
Changed condition for combination of WLines into one.
WLine would be excluded from consideration for merging, if one of its middle points between vertices is out of domain (does not lie on both surfaces).
This problem occurs because of obtaining 2 ALines which share same vertex on the seam edge.
There should be 2 different vertices with same(or almost the same) 3d parameters, but
with different UV parameters because of periodic surface.
Current fix allows to avoid the same vertices on seam edge and also checks the next vertex.
Added consideration of predicted next point to avoid skipping tha point which is not on seam edge.
Added test case for #33702
Added option to dump only a selection of zlayer's content.
Changed zlayers redraw and render method for selection of layers to render.
Added filters for layer parsing.
Modified vdump command.
Added test with multiple dumps for comparison.
Added option to dump shadow maps.
Added property to SelectableObject for selection focused on display priority.
Modified SelectMgr_ViewerSelector CompareResults based on the focus priority property.
Added display priority to the sorting criterion
Added tests for multiple types of sensitive entities.
Modified vpriority command to change an object's selection priority.
Added flag to transform persistence to handle axial scaling.
Modified manipulator's zoom transform persistence to fit in axial scaling events.
Added tests for cases 27832 and 33514.
Logic change on Graphic3d_TransformPers::Apply for Graphic3d_TMF_AxialScalePers.
Logic fixes in AIS_Manipulator to integrate axial scale in both zoomable and unzoomable states.
Completed the stop transform action when dragging manipulator with mouse.
Added context redisplay for update of interactive object sensitive areas.
Added test.
Added protection against null pointer dereferencing.
Modified BRepOffset_MakeOffset::MakeThickSolid method.
Fixed the problem with negative volume values.
Fixed several unit tests and added a new one.
Handling of special case found on some STEP files produced by FPX Expert 2013 (PCB design system):
edge curve is line displaced from its true position but with correct direction;
we shift the line in this case so that it passes through vertices correcty.
Protection against possible exception in writing XDE.
ProjCurve3d and BRepAlgo_FaceRestrictor::Perform functions should not continue to work and should terminate if the BRep_Tool::Curve function returns null pointer.
Added a transfer for ShapeRepresentationRelationship in Transfer of MappedItem method,
in order to support link of components according to ISO 10303-203-2003.
Datum reading changed in ReadDatums() method:
using DatumSystemAP242 (DatumSystem or DatumReference) array
instead of DatumSystem array (DatumReference)
The new transform persistence mode, with flag `Graphic3d_TMF_OrthoPers`, can be combined (bitwise OR operation) with the other persistence modes (2D, Trihedron or Zoom/Rotate Persistence) to make objects be rendered with orthographic projection when it is on a view with perspective projection.
If the view already uses orthographic projection, there will be no difference.
This feature was implemented to fix ViewCube being distorted when view with perspective projection changes size.
